Seed starts to germinate only under certain conditions. The optimum temperature at which seeds germinate best varies with different kinds of seed. The optimum temperature for the germination of wheat, for instance, is about 270C. Cotton and corn germinate best at about 350C.
Seeds of all crops need enough air for germination as oxygen is necessary for certain chemical reactions which take place in the plant food in the seed.
These reactions take place only, when water is present. So, moisture is also necessary for the germination of seeds.
This, a seed does not germinate: 1) if the temperature is not proper, 2) if there is not enough moisture and air in the soil.
